' '9 Claims; -(o1.200 134 Our invention relates to fuse clip, clamps. In practise, it is well known, that. theconven- 'tionalfuse clip when engaged with the terminal of a fuse does notsufiicientlygrip the terminal to establish a firm electrical contact, resultingin the creation of an-arc between the terminal and fuse clip which causes heating and burning of the fuse.

It isan object of the invention to providea 1o clamp adapted to cooperate with the fuse clip, for clamping the clip securely in engagement with the terminalof the fuse, insuring a perfect electrical contact, so'as to prevent the creation of an are between the terminal and clip.;

A further object of the invention is to provide a clamp of the above-mentioned character which maybe quicklyaand readily engaged with the fuse clip and which embraces the wholeof that portion of the clipwhich engages the terminal of the fuse, thusgestablishing a uniform con-v tact between the terminal and fuse clip.

A still further object of the invention is to provide a fuse clip clamp having pivoted clamping jaws adapted to engage the fuse clip and a piv oted lever operable to move the jaws into firm clamping engagement with the fuse clip.

Another object of the invention'is to provide a device of the above-mentioned character which is simple and durable in constructiom reliable and efiicient. in use and inexpensive to manufacture. Other objects and advantages of the invention 1 Will be apparent during the course of the following description. I s

'In the accompanying drawing, forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a side elevation view of the clamp, Fig. 2 is an end view of the clamp, when in clamping engagement with a fuse clip, a

Fig. 3 is a sectiontaken on lines 3-3 of Fig. 2, Fig. 4 is a top View of the clamp, Fig. 5 is an enlarged section takenon lines 5-5 of Fig. 1,

Fig. 6 is a perspective View of the supporting plate for the clamping jaws, and, Fig. 7 is a perspective view of one of the clamping jaws.

In the drawing, wherein for the purpose of i1- 50 lustration, a preferred embodiment of the invention is shown, the numerals 5 and 6, denote a pair of clamping jaws, which are formed from rectangular plates having their longitudinal edges bent to provide flanges 7, the flanges ofeach jaw having alined openings 8, above the intermediate portion thereof. The jaws are; pivotally supportedon opposite sides of the supporting plate 9, which at each end is provided with upturned cross bars-10 and 11,, which extend over the flanges '7, a'ndha've openings 12 and 13 ,respectively, adapt; ed to aline with the openingsBofthe flanges and.v

.pintlepins 14 extend through-theopenings'pivotally-mounting the jaws on the'supporting plate in confronting relation- Thecross-bar ll ex-y.

tends upwardly to a point adjacent the upper 5;

ends of, the jaws and is provided witha central slot 15, in its upper edge-to receive one .end'of the clamping lever 16 which is pivotallysupa portedby the pivot pinl'l, extendingthrough the handle and lugs 18, bent outwardly from the sides of the slot. The lever is constructed of insula: tion materialandis of such-,lengthas to extend a substantial distance-beyond the jaws-when swungdownwardly between the jaws into operativepositiom; The lower-101' igripping; faces-of the jaws. are knurled, as at 19, and are of sufficient length and .width to grip the entire portion of the fuse clip which contacts with'the terminal of the fuse and each jaw face beneath the supporting plate 9, is so formed with a shoulder 20'extending transversely "of the face, over which the bent upper ends of the fuse cli'pengage, as shown'in dotted lines in Fig. 2. The upper faces of the jaws are formed with opposed grooves or depressions 21, more 5 clearly shown in Fig. 5, to receive and secure the lever 16 in operative position when swung downwardly between the jaws. There may be one or more sets of grooves extending transversely of the faces, at an angle to the vertical axis of the jaws, the lower set of grooves being slightly raised with respect to the upper set of grooves, so that by moving the lever from one set of grooves to the other the pressure on the jaws may be varied, thus permitting the gripping force of the jaws on the fuse clip, to be increased or decreased. In use, the clamp is positioned with the gripping facesof the jaws engaged with the outer faces of the contacting portions of the fuse clip, which receive theterminal of the fuse, and upon swinge 109 ing the clampinglever lfi, downwardly between the upper faces of the jaws, the gripping faces of the jaws are moved inwardly, forcing theclip into firm electrical contact with the fuse terminal.

v'Ine'grooves 21, formed in the'upper faces of the 05 ing. adapted to swing between said jaws .to

junction with knife type fuse clips, but it is apparent the same may be used with ferrule type fuse clips without material alterations.

It is to be understood that the form of the invention herein shown and described is to be taken as a preferred example of the same and that certain changes in the shape, size and arrangement of, the parts may be made without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described our invention, claim:

plate, a pair of clamping jaws pivotally mounted on opposite sides of said plate intermediate their length and a pivotally mounted lever carried by said supporting plate andadapted to swing between said jaws to move said jaws into clamping position.

2. A fuse clip clamp comprising a supporting plate, a pair of clamping jaws pivotally mounted on opposite sides of said plate intermediate their length and 1 a lever having one end pivotally mounted on one end of said plate, said lever bemove said jaws into clamping position. i

3. A fuse clip clamp comprising a supporting plate, a pairlof clamping jaws pivotally mounted onopposite sides of said plate, intermediate their length, a lever pivotally mounted on said plate adapted to operate between said jaws, to move said jaws into clamping position, and means for holding said lever in operative position.

4. A fuse clip clamp comprising a pair of pivotally mounted clamping jaws, a pivotally mounted lever operable betweenthe jaws tomove said jaws into clamping position, and means on said jaws for holding said lever'in operative position.

5. A fuse clip clampcomprising a pair of pivotally mounted clamping jaws, and a pivotally mounted lever adapted to operate between erable between the upper ends of said jaws to move the. jaws into clamping position.

' 7. A fuse clip clamp comprising a supporting plate having upturned cross bars at each end, a pair of jaws pivotally mounted between the cross bars on opposite sides of said plate, said jaws being pivoted intermediate their length, and a clamping lever having one end pivotally mounted on one of the cross bars adapted to operate between the upper ends of said jaws to move the jaws into clamping position, the upper ends of said jaws having grooves to receive and secure said lever in clamping position.

8. A fuse clip clamp comprising a pair of opposed clamping jaws, means pivotally supporting said jaws and a lever having oneend pivotallymounted on said means and adapted to swing between said jaws to move said jaws into clamping position. V

9. A fuse clip clamp comprising a; supporting plate having angularly bent cross bars at each end, a pair of jaws pivotally mounted on opposite sides of said supporting plate and a clamping lever for having onee'nd pivotally mounted on one of the cross bars, said lever-beingoperable between the upper 'endsof sai-djaws to move the jawsinto clamping position. 1
